As a Low - Input - Impedance Preamplifier for Current - Division Use
By grounding the usual inputs of a 733 amplifier chip and driving one of the gain-control pins, one obtains a common-base input stage with an input impedance of about 20 ohms. This can be used as an inexpensive current-division preamp and, in large multichannel systems, will probably not limit the performance. In the current-division method of coordinate measurement one observes the (integrated...

متن کاملAn integrated capacitance bridge for high-resolution, wide temperature range quantum capacitance measurements.
We have developed a highly sensitive integrated capacitance bridge for quantum capacitance measurements. Our bridge, based on a GaAs HEMT amplifier, delivers attofarad (aF) resolution using a small AC excitation at or below k(B)T over a broad temperature range (4-300 K). We have achieved a resolution at room temperature of 60 aF/√Hz for a 10 mV ac excitation at 17.5 kHz, with an improved resol...
متن کاملAsymmetrical-fed RHCP Wide-Band Slot Element for X-Band applications
An outstanding square slot element, for x-band wireless applications with asymmetric coplanar waveguide fed (CPW) is proposed. Various shapes of metallic strips are utilized as grounded stubs for providing Right Hand Circular Polarization (RHCP) functionality and wide-band properties. By adjusting the proposed stubs and hook-shaped radiator, length and positions, wider impedance band width is o...
متن کاملSelf-Equalized Distributed Amplifier for Wide Band Optical Transceivers
A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.
